STOVE AND GRATE THEREFOR.

SPECIFICATION forming Vpart of Letters Patent No. 743,861, dated November 10, 1903.

Applicant and June 12, i902'. sem no. 111,417. un maar To @ZZ wiz/m it may concern:

Be it known that I, JOSEPH GREGORY, a citi zen of the United States, residing at 'Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Stoves and Grates Therefor, fully described and represented in the fol lowing-specification and the accompanying drawings, forming a part of the same. ro This invention relates to improvements in cooking-stoves and grates therefor.

The improvements of the present invention have reference'particularly to stoves of the class commonly known as oil and gas i5 stoves, and they will for that reason and for convenience be hereinafter described in detail in connection with stoves of this class,

although, as will hereinafter appear, certain features of the invention are applicable to zo stoves in which Wood or coal isused as the fuel.

As cooking-stoves, and particularly oil and gas stoves, are now commonly constructed they are open to the objection that when liquid boils over or is spilled upon the sides of` the cooking-receptacle it runs down the sides of the receptacle and then for a certain distance along its bottom until it reaches the lowest point on the latter, when it drops into` 3o the chamber beneath, forming the seat of combustion or combustion-chamber. In the case of stoves using wood or coal as fuel this may result in a very unpleasant odor, while in the case of oil and gas stoves the edect is l additionally to make the flame flare, with spilled upon or boil over the sides of the coolzl.

ing-receptacle will be prevented from falling into the am'eor upon the combustionchamber.

In the accompanying drawings, Figure l is 5o a sectional elevation of' an oil-stove equipped chamber.

`Way with the combustion `chamberof the stove, comprising a vaporizer and burner 2 6o and an outer inclosing casing 2, while 3 represents-the grate, and i the frame, of the stove. Y The grate 3 consists of radial gratebars 7 and outer and inner annular grate- "bars 8 9, and it is supported in position upon 65 the stove by a ring l2 resting upon the upper edge of the frame 4c and. upon which in Y turn the outer ends of the radial grate-bars 7 rest, as shown in Fig. l. The grate 3 is also provided with aoentral plate 6 of a size to per- 7e mit the passage of the flame around it and into contact with the cooking-receptacle and is also provided beneath said plate with an annular plate or shelf 10, having a central flame-opening ll, there beinga suitable air space or opening between plates 6 and 10 and also between plate l0 and the combustion-chamber. The plate 6 preferably extends slightly above the upper edge of the grate-bars 7 8 9, so as to act as the support for the cooking-receptacle. 8o This arrangement of plate 6 may be departed from, however, as while it is desirable that such plate should serve as a support for the receptacle. its principal function is that of shielding or protecting the burner and combustion-chamber from such liquid as may be spilled upon or boil over the sides of the cooking-receptacle by preventing such liquid from droppingfrom the bottom of the receptacle into or onto the burner or combustion- 9o With this latter functionin view I construct the support 6 in the form of a solid or imperforate plate, as shown, so that Y should any liquid be spilled upon or boil over the sides of the receptacle and travel thence (as it will) along the bottom of the receptacle it will either be arrested by the outer edge of the plate 6 or, if not arrested thereby, be caught upon the upper, surface thereof and speedily evaporated or caused to pass outroo Wardly over the edge of the plate as it collects on the upper surface thereof. If the under side of the plate 6 were, like the bottom of a cooking-receptacle, substantially [iat or plain, the liquid thus arrested by or passing outwardly over the edge of the plate would of course travel inwardly along the bottom of the plate 6 until it reached the lowest point thereon, whence it would drop into or onto the burner2. Thisinward movement of the liquid along the bottom of the plate 6 is prevented, however, by providing the plate 6, at or near the edge thereof, with a depending portion or curtain 13, the lower end of which, as will be observed, extends below the bottom face of the plate 6. The result of this construction of the plate 6 is that the liquid arrested by or passing outwardly over the edge thereof will travel down the depending portion or curtain 13 and be prevented by suoli depending portion or curtain from traveling inwardly along the bottom of the plate, the liquid thuscollecting on the depending portion or curtain 13 dropping therefrom onto the stove-support outside the casing 2a of the combustion-chamber or being delivered to the cone-shaped plate or shelf 10 provided beneath it, this plate or shelf 10 being downwardly and outwardly inclined and acting as a catcher and deector for the liquid dropping from plate 6 and from which the liquid drops to the support upon which the stove happens to be mounted. The plate or shelf 10 is of such width and so arranged with relation to the curtain 13 of plate 6 that its inner edge extends inside the depending portion or curtain 13 of plate 6 and its outer edge extends beyond or outside the casing 2a, with the result that 4o all the liquid dropping from the plate 6 will be caught by the plate or shelf 10 and be deflected thereby downwardly and outwardly to its outer edge, whence it will drop outside the casing 2iL of the combustion-chamber.

As the plate 6 will have a tendency as the flame impinges against its under side to spread the flame outwardly and away from the cooking-receptacle, the inner annular bar 9 of the grate is in the construction shown 5o arranged so as to act as a arne-detlector for `directing the flame thus spread outwardly by plate 6 inwardly and upwardly toward the cooking receptacle. For this purpose the grate-bar 9 is arranged in line with the opening or space between plates 6 and 10 and is provided with avertical inner face terminating a short distance below plate 6 and its depending portion or curtain 13, as shown, the lower edge of said bar being also below the 6o inner edge of plate or shelf 10, so as to prevent the passage between it and said plate or shelf of the darne when spread outwardly by plate 6.

The grate thus described, with its plate 6 and plate or shelf 10, may be formed in a variety of ways without departing from the invention, broadly considered; but I prefer to make the several parts` integral, with the exception of the plate 10, as shown in the drawings, the plate 6 and grate-bars 7, 8, and 9 being formed in a single casting of iron, with the plate lO securedv thereto by means of lugs 14 cast upon the grate-bar 9 and bolted to plate 10.

As before stated, it is preferred to arrange the plate 6, as shown in Figs. 1, 2, and 3, so that it will serve as the support for the cooking-receptacle; but it may be so arranged as not to perform this function without departing from the present invention, broadly considered, as illustrated in Fig. 4, which will now be described. In the organization illustrated in this figure of the drawings the plate 6 and liquid-catcher and deflecting-plate 10, instead of being borne by the grate 3, as in the preceding figures, are supported from the burner-casing 2a, the plate 6 being bolted to plate 10 and the latter in turn bolted to the upper edge of casing 2a, which is provided with suitable air-passages 2l. In this organization also the annular grate-bar 9 is not utilized as a means for detlecting the flame inwardly and upwardly toward the receptacle after it leaves the under side of plate 6, an annular plate 9a being provided for this purpose, which is bolted to plate or shelf 10. In an organization such as this, with the plate 6 and plate or shelf 10 detached from the grate 3, such plates 6 and 10, as well as the annular llame-deiecting plate 9a, will preferably be formed of sheet metal.

In the organization illustrated in Fig. 4 also the lower end of the burner and Vaporizer 2 below the combustion-chamber and the lowerend of the burner-casing 2 are partially closed by an air screen or retarder 15, consisting of a perforated plate the function of which is to retard the entrance of airinto the burner and vaporizer and the burnercasing and to thus cause it to enter in a steady and uniform manner.
